Summary:                    Voicemail "greetings only" feature
Description: 
The expected behaviour of a "Greetings only" Voicemail is to play the
user's greeting message and to hang up without recording anything.
This feature, that exists on some PBX, allows users who don't want voice 
messages to easely setup a failover announcement.

So why using the Voicemail application instead of playing a recording ? 
Mainly for simpleness reasons:
- It gives a unique dialplan entry point to all users (those who wants a 
recorder and those who don't) when they want to configure their greeting 
messages.
- It keeps the dialplan simple, as the user failover destination is 
always the Voicemail application.

As I didn't find such a feature in the voicemail documentation, my first 
guess was to set the user maxmsg to zero. Next I looked more closely at
app_voicemail.c and realized that zero is not a valid value.

So I wrote a small patch for app_voicemail.c to support maxmsg=0 and act 
as a "Greetings only" VM in the appropriate case. I hope you will find
this feature interesting :)
